Description

The module is a box formed from two printed circuit boards mounted on a three-sided metal frame. The circuit boards are mounted facing each other with the circuit sides out. Each board has a male connector with two rows of 15 pins attached to one edge. These two connectors form the fourth side of the frame, on the bottom of the module. The top of the frame has two protruding 'ears,' presumably to facilitate extraction of the module from a backplane. The top also has a single banana-plug socket, and a hole presumably for air circulation. There is a matching hole in one side of the metal frame, which aligns with the holes in the plenums of the backplane, object 102735636. One of the boards is just over half-height, revealing two tube sockets mounted perpendicular to the other board, so that plugged-in tubes are contained within the module. One socket contains a vacuum tube and the other contains a plastic Technitrol module. The edge of the short board has been color-coded with a wide black stripe.
